BOX-FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 819,651, dated June 9,1885.

I Application filed July 5, 1884. (No model.) I

To all whom it may concern:

Be it known that I, GEORGE WILSON, a citizen of the United States,residing at Toledo, in the county of Lucas and State of Ohio, haveinvented a new and useful Box-Fastening, of which the following is aspecification.

This invention relates to that class of boxfastenings which are commonlyused on boxes for shipping beer, soda, and other bottles, in which adetachable lid is looked upon the box by means of an internal concealed,and consequently protected, fastening, and which is operated to unlockor release the lid through a hole in one of the sides of the box.

The object of my invention is to provide a simple, cheap, and durablefastening, which shall be self-locking by the act of closing the lidupon the body of the box, and which shall be adapted to be sealed, ifdesired, by the use of an ordinary car-door compressionseal. I at tainthese objects by the mechanism illustrated in the accompanying drawings,in which- Figure 1 is a vertical end section of a box having attached myimproved fastener. Fig. 2 is also a vertical end section having attachedmy improved fastener and representing abox as it appears when the coveris open. Fig. 3 is a plan of the striking-plate which forms the coverpart of my fastener on line A, Fig. 6. Fig. 4 is a sectional view of thestriking-plate on line B, Fig. 3. This view also shows the upperextremity of the locking-spring and the perforation therein. Fig. 5 isaportion of the front elevation on line D, Fig. 1. Fig. 6 shows anelevation of the metallic part of my fastener as it appears when whollydetached from the box, and is similar to the metallic part shown inFig. 1. Fig. 6 is taken on line E, Fig. 4. Figs. 7 and 8 are two viewsof a spring made of wire instead of steel plate, which latter are mostcommonly used.

Similar letters refer to similar parts through out the several views.

In the drawings, F represents a spring, preferably made of fiat steelplate, as shown in Figs. 1, 2, 3, 4, and 6 but a very desirable springis made of wire, as shown in Figs. 7 and 8. This spring F has a suitablehole, 0, or perforation in its upper extremity, the office of screw,nail, or staple at I, Figs. 1, 2, 6, 7, and

8, is only partly driven into the wood to the extent of allowing therequisite movement of the spring F, but no more, and is an effectualcheck against the careless forcing of the spring F beyond its springingcapacity, and is a valuable adjunct for this purpose, while it alsoserves the purpose of keeping the spring F in proper vertical position.

The spring F maybe slightly bent, as shown in Figs. 1 and 2, but thisbend is not essential.

The striking-plate S (shown in Figs. 3 and 4) is also one of theprincipal features of this invention, being made in nearly asemicircular form, with a central perforation, 0, Figs. 4 and 7, throughwhich the upper extremity of the spring F may pass to nearly a levelposition with the top of the body of the box, while the outside rim ofthe said plate S has abundant room for securing screws or nails. Theplate S is also provided with a catch bolt or lug, N, of a form adaptedto automatically pass through the hole or perforation O in the spring Fby the act of closing the cover J of the box.

The spring F is operated upon for the purpose of releasing the coverJ bypassing through the hole K in the body of the box H a pin, L. This pin Lhas a head on its inner end and a hole through its outerend, the head,by being larger than the hole K, preventing the pin from passing outwardand being lost, the hole in the pin admitting of the use of a sealing-wire, as shown in Figs. 1, 5, and 6.

I am aware that prior to my invention boxfasteners having straight fiatsprings and bent flat springs turned at various angles at their upperextremities and used in combination with flat striking-plates have beenknown and used; also various devices for concealed fast- 2. Thecombination, with the box H and the 15 'catchspring' F, having aperforation, O, in its upper extremity, of the flat striking-plate S,with its central perforation and its ofisetting lug or catch-bolt N, thepin L, having a retaining-head on its inner end and a hole near 20 itsouter end, substantially as and for the purpose described.

GEORGE WILSON.
